As wildfires ignite, shift, and are eventually extinguished, NOAA’s satellites are providing round-the-clock monitoring of wildfire locations and intensities. This image shows some of the 11,365 wildfire targets identified by NOAA and NASA satellites from August 10-15, 2012 over North America. Each tiny red pixel represents one fire target detected over those 144 hours. The infrared sensors on the GOES, POES, Aqua/Terra, and Suomi NPP satellites can detect the heat emitted by wildfires and map their locations with greater than 1 kilometer accuracy.
